i have a 15 dci clio where the injector is puffing out air and oily substance around it ,
its the injector nearest the cambelt i had it taken out and cleaned and the air noise stopped for a couple of days but its back in it again i have looked at a haynes manual and it has said when you remove an injector to replace the flame sheild washer that is located at the bottom of injector and it also says to replace the sealing shim between the head and injector but it doesn't show in manual how this is done,
I'm looking for a bit of info how to replace this sealing shim as i think this will sort problem does this involve taking head off or what has anyone out there had this done or had similiar problem
thank any help most welcome

Replacing a seal does not require taking the head off.

I believe the most common layout on diesel injectors is such, that you must remove the injector carrier, i.e. the outer large diameter insert, if you want to remove the flame rings.

Depends then on how much you removed when the injector was removed.

TBH I've never, ever replaced these rings on the diesels I've owned and driven. Only did it once on SIL's car because the injectors were replaced.

Have you tried swapping the leaking injector with one of the other 3 injectors ? That would tell you if its related to the injector or the feed pipe connector.

If you need some of these bits, find a diesel garage. Dont use your Renault dealer, as they would rip you for these bits, if they stock them at all.

Yes, the seals can be a bit fiddly to get out !
